摘要
在山西省高寒区进行日光温室大棚枣栽培试验,试验表明,设施栽培能够达到或略超适生区太原市、晋中市露天栽培的条件,完全可以满足枣树生长发育的要求,达到经济栽培的目的。1月15日至30日为扣棚时间,7月以前的保温调控技术是关键技术。与适生区露天栽培相比较,萌芽期为3月下旬,提前了20 d^30 d;新梢生长提前10 d^15 d,但其它物候期与实生区接近。2年生时0.5 m×1.0 m园内鲜枣产量达1 067.2 kg/667 m2;1 m×2 m园内鲜枣产量达500.3 kg/667 m2,经济效益十分显著。
Taking experiments of sunlight greenhouse cultivation of jujube in colder area in Shanxi province,protected cultivation could reach or surpass open-air cultivation of suitable region in the city of Taiyuan and Jinzhong,and satisfy completely the requirements of the jujube tree growth to reach economic cultivation. Tent-buckling stage was between 15 to 30 January. Thermal control technology before July was the key technology. Compared with suitable area open-air cultivation,bud germinating period was in late March which was ahead of schedule for 20 ~ 30 days,and new shoots grew 10 ~ 15 days in advance,but the other phenological phases were closer to that of the suitable area. In 0. 5 m × 1. 0 m garden of 2 years old plant,the fresh jujube production reached 1 067. 2 kg /667 m2,and 1 m ×2 m garden reached 500. 3 kg/667m2,the economic benefit was significant.
